Abstract: Present research paper “Study of Fillet Stresses on Crankshaft and Modal Analysis” is a complete Finite Element Analysis of Crankshaft and validate results are theoretical analysed for 4-cylinder, 4-stroke, turbocharged diesel engine with in-line through crankshaft that used the most of automobile companies for the model analysis. In this study the Crankshaft torsional vibrations are analyzed by using the numerical simulation methods and Causes of failures of Crankshaft. For this research Holzer method is used to determine the natural frequency and mode shape of multi-rotor torsional vibration system. Various Pressures at different crank angles are also taken in the account of analysis. .This study is an important effort to develop the scientific and technical understanding for the failure Crankshaft of any Engine under the line of laws of mechanics.

Keywords: Modal Analysis, Torsional Vibration, Fillet Stresses, Natural Frequency.
